1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 11AUG24 1800Z, TROPICAL STORM 06W (MARIA) WAS LOCATED 
NEAR 38.3N 142.9E, APPROXIMATELY 149 NM SOUTH-SOUTHEAST OF MISAWA, 
JAPAN, AND HAD TRACKED NORTH-NORTHWESTWARD AT 06 KNOTS OVER THE PAST 
SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 50 KNOTS 
GUSTING TO 65 KNOTS. SEE REF A (WTPN31 PGTW 112100) FOR FURTHER 
DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 91W) PREVIOUSLY LOCATED NEAR 
22.1N 135.6E IS NOW LOCATED NEAR 21.9N 135.9E, APPROXIMATELY 519 NM 
EAST-SOUTHEAST OF KADENA. ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND 
A 112058Z GMI 89GHZ SATELLITE IMAGERY DEPICTS AN AREA OF PERSISTENT 
DEEP CONVECTION OBSCURING A CONSOLIDATING LOW LEVEL CIRCULATION CENTER 
(LLCC). ENVIRONMENTAL ANALYSIS REVEALS AN AREA THAT IS FAVORABLE FOR 
DEVELOPMENT WITH WARM (28-29C) SST, LOW VERTICAL WIND SHEAR (10-15KTS) 
AND GOOD EQUATORWARD OUTFLOW ALOFT. GLOBAL MODELS ARE IN GOOD 
AGREEMENT SHOWING GRADUAL MODEL DEVELOPMENT THAT 91W WILL CONTINUE TO 
TRACK NORTHWARD OVER THE NEXT 48 HOURS. MAXIMUM SUSTAINED SURFACE 
WINDS ARE ESTIMATED AT 18 TO 23 KNOTS. MINIMUM SEA LEVEL PRESSURE IS 
ESTIMATED TO BE NEAR 1000 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A 
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO 
MEDIUM.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY:
       (1) THE AREA OF CONVECTION (INVEST 95W) PREVIOUSLY LOCATED NEAR 
27.1N 154.9E IS NOW LOCATED NEAR 27.8N 155.2E, APPROXIMATELY 910 NM 
EAST-SOUTHEAST OF YOKOSUKA. THE SYSTEM IS CURRENTLY CLASSIFIED AS A 
SUBTROPICAL CYCLONE, GENERALLY CHARACTERIZED AS HAVING BOTH TROPICAL 
AND MIDLATITUDE CYCLONE FEATURES. ANIMATED MULTISPECTRAL SATELLITE 
IMAGERY DEPICTS LOW-LEVEL CLOUD LINES WRAPPING INTO A FULLY-EXPOSED 
LOW-LEVEL CIRCULATION, WITH ISOLATED DEEP CONVECTION SHEARED TO THE 
EAST. A 110320Z AMSR2 WINDSPEED IMAGE AND A 110006Z ASCAT-C IMAGE 
REVEAL A HIGHLY ASYMMETRIC WIND FIELD WITH 30-35 KNOT WINDS DISPLACED 
WELL TO THE SOUTH AND EAST OF THE CENTER. AS EVIDENT IN THE TOTAL 
PRECIPITABLE WATER IMAGERY, 95W IS LOCATED ALONG THE EASTERN PERIPHERY 
OF THE MONSOON GYRE, WITH A HIGHLY ASYMMETRIC, EXTENSIVE REGION OF 
DEEP MOISTURE EXTENDING WESTWARD TO 125E. GLOBAL MODELS INDICATE THE 
SYSTEM WILL TRACK POLEWARD UNDER THE STRONG UPPER-LEVEL LOW OVER THE 
NEXT TWO DAYS WITH GRADUAL WEAKENING. FOR HAZARDS AND WARNINGS, 
REFERENCE THE FLEET WEATHER CENTER SAN DIEGO HIGH WINDS AND SEAS 
PRODUCT OR REFER TO LOCAL WMO DESIGNATED FORECAST AUTHORITY. MAXIMUM 
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 30 TO 35 KNOTS. MINIMUM SEA 
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 995 MB. THE POTENTIAL FOR THE 
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS 
REMAINS MEDIUM.
      (2) NO OTHER SUBTROPICAL SYSTEMS.
2. SOUTH PACIFIC AREA (WEST COAST OF SOUTH AMERICA TO 135 EAST):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA 1.B.(1) TO
MEDIUM.//
